ProCamera 8 + HDR, the photo, video, and editing app by Cocologics, recently updated to add Apple Watch controls and a few other fun functions.
With the Apple Watch app you can trigger the shutter release with a tap of your finger. This means you'll be able to take more exciting selfies or strangely angled shots as you can place your iPhone anywhere you like and remotely take the picture. The watch shows you the viewfinder as well, so you can line up your shot just by looking at your wrist.
The update includes Protimer, which lets you set your camera to either delay a shot, take a sequence of shots, or have an interval of time between consecutive photos. You'll also get the advanced HFR video recording, giving you a ton of different frame rates to choose from, and a configurable camera selector that lets you rearrange your displayed icons to make it easier to find your favorite modes.
The newly updated ProCamera 8 + HDR is available for $3.99.
